The FESTO QS-G1/4-8 is a straight push-in fitting that connects Ø8 mm pneumatic tubing to a G1/4 male-threaded port. Tubing locks in on insertion and releases with the blue release ring (push-pull principle). The nickel-plated brass body and factory-fitted sealing ring on the thread make it suitable for compressed air and water lines in machine building and factory automation.
